Guide coverage: patches through 1.0.9
Weapons
First buy a weapon strong enough for the current island’s boss; boat upgrades can wait. To unlock Fully equipped, install a sight, barrel attachment, laser sight, and extended magazine on the same gun. The shotgun cannot unlock it because it has no extended-mag slot.
Guns
| Gun | Cost | Sell | Damage | Shot s | Pellets | Spread | Mag | Auto |
|---|---|---|---|---|---|---|---|---|
 Assault Rifle | 20000 | 9000 | 40 | 0.07 | 1 | 0 | 30 → 40 | Yes |
 Sniper Rifle | 3800 | 1800 | 200 | 1.00 | 1 | 0 | 5 → 8 | No |
 Shotgun | 150 | 60 | 3 | 0.22 | 25 | 6 | 2 | No |
 Pistol | 50 | 20 | 25 | 0.15 | 1 | 0 | 10 → 17 | No |
 SMG | 650 | 300 | 24 | 0.05 | 1 | 0 | 30 → 40 | Yes |
Damage is listed per bullet; each shotgun shot fires 25 pellets. The shop UI incorrectly shows 0 damage for most guns. This table uses the actual values from each weapon’s bullet-upgrade data.
Mag = shots before you have to reload. The arrow is the magazine size with the Extended Mag attachment fitted (its price: pistol $90, SMG $320, sniper $1200, assault rifle $5400). The shotgun has no extended magazine.
Attachments
Gun-shop attachments and their price per gun. Sights, barrel attachments, laser, and extended mag are bought per weapon — a compensator for the pistol does not fit the rifle.
| Attachment | Effect | Pistol | Shotgun | SMG | Sniper | Rifle |
|---|---|---|---|---|---|---|
| Red Dot Sight | Easier to hit targets while aiming | 310 | 280 | 460 | 640 | 5500 |
| Sniper Scope | Easier to hit distant targets while aiming | 940 | 650 | 940 | 1200 | 4300 |
| Compensator | Moderately reduces recoil | 400 | 220 | 600 | 500 | 3000 |
| Suppressor | Significantly reduces recoil | 2500 | 1800 | 2500 | 2500 | 8000 |
| Laser Sight | Shows where the weapon is pointing, making hipfire easier | 100 | 140 | 280 | 1600 | 4800 |
| Extended Mag | Increases ammo count in magazine | 90 | — | 320 | 1200 | 5400 |
| Iron Sight | Removes any sight attached to weapon | 0 | 0 | 0 | 0 | 0 |
“—” means the gun has no such slot (the shotgun has no extended mag). Iron sight is free and just removes a fitted scope. Compensator and suppressor share one barrel slot; red dot and sniper scope share one sight slot.
Bullet upgrades
Every gun upgrades 12 times at the gun shop (Upgrade Bullets). Each tier raises per-bullet damage; you pay the listed price to step up one tier at a time. Island cap: Lighthouse 3, Forest 6, Desert 9, Rocks & Volcano 12.

Melee
The game data contains two knife variants and two knuckle variants. Their prices and force values differ, so they are separate shop items rather than duplicate table rows.

|---|---|---|---|---|
 Knife | 1 | 75 | 500 | 1.5 |
| Knife | 2 | 45 | 100 | 1.5 |
 Brass Knuckles | 1 | 24 | 100 | 1.5 |
| Brass Knuckles | 2 | 40 | 1750 | 1.5 |
